Configuring Port Bonding

Port bonding is a well-established method for improving the performance and resiliency of a physical data connection. Port bonding combines two or more ports into a single logical interface whose potential bandwidth is the sum of the bandwidths of the individual ports. Additionally, if one of the ports in the group should fail, the interface remains operational (but with reduced maximum performance).

Beginning with Release 4.1.3, VDS-VR supports port bonding for the Management and Locate ports of a VDS-VR Recorder. This section provides procedures for configuring such support.

Configuring Management Port Bonding

To configure Management port bonding on a VDS-VR Recorder, do the following:

Step 1 Edit /home/isa/.arroyorc and replace “eth0” with “bond0”:

#vi /home/isa/.arroyorc

self 5

groupid 1620

serverid 16

partno CDE460-4R3

mgmtif bond0

dbdomsock /tmp/isadb

bmsvendor rtspgeneric

Step 2 Edit /arroyo/test/recorder/setupfile and replace “eth0” with “bond0”:

# vi /arroyo/test/recorder/setupfile

ndvr 1

serverid 16

groupid 1620

management bond0

ingest eth4

ingest eth6

control bond0

default control bond0

localip 00a4a1110

ftpout if bond0 max utilization mbps 0 max sessions 0

Step 3 Create a new file /etc/sysconfig/network-scripts/ifcfg-bond0 and configure the IP address and net mask for the management port:

# vi /etc/sysconfig/network-scripts/ifcfg-bond0

DEVICE=bond0

BOOTPROTO=static

IPADDR=10.74.17.16

NETMASK=255.255.255.0

ONBOOT=yes

USERCTL=no

BONDING_OPTS="miimon=100 mode=1”

Step 4 Edit /etc/sysconfig/network-scripts/ifcfg-eth0 and replace actual IP address with “bond0”:

#vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=static

MASTER=bond0

SLAVE=yes

ONBOOT=yes

Step 5 If /etc/sysconfig/network-scripts/ifcfg-eth1 doesn’t exit, create it with the following lines. If it already exists, just edit it and replace “IPADDR=<ip address>” with “MASTER=bond0”:

# vi /etc/sysconfig/network-scripts/ifcfg-eth1

DEVICE=eth1

BOOTPROTO=static

MASTER=bond0

SLAVE=yes

ONBOOT=yes

Step 6 Edit /etc/sysconfig/network and replace “eth0” with “bond0”:

# vi /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=CDE460-17-16

GATEWAY=10.74.17.1

GATEWAYDEV=bond0

NOZEROCONF=yes

Step 7 Reboot the Recorder:

# reboot

Step 8 Connect eth1 to the same VLAN with eth0 on the Switch.

Step 9 After the Recorder boots up, ping the gateway IP on the recorder the server:

# ping 10.74.17.1

PING 10.74.17.1 (10.74.17.1) 56(84) bytes of data.

64 bytes from 10.74.17.1: icmp_seq=1 ttl=255 time=2.69 ms

64 bytes from 10.74.17.1: icmp_seq=2 ttl=255 time=0.322 ms

64 bytes from 10.74.17.1: icmp_seq=3 ttl=255 time=0.353 ms

--- 10.74.17.1 ping statistics ---

3 packets transmitted, 3 received, 0% packet loss, time 2000ms

rtt min/avg/max/mdev = 0.322/1.121/2.690/1.109 ms

Step 10 Test the management port bonding as follows:

a. Shut down eth0 and make sure SSH connection remains:

# ifconfig eth0 down

# ifconfig eth0 up

b. Shut down eth1 and make sure SSH connection remains:

# ifconfig eth1 down

# ifconfig eth1 up

c. Shut down eth0 & eth1 and make sure SSH connection remains:

# ifconfig eth0 down

# ifconfig eth0 up

# ifconfig eth1 down

# ifconfig eth1 up

Configuring Locate Port Bonding

With VDS-VR, there are two possible options for configuring Locate port bonding:

All ports are 10 GbE Locate ports assigned to separate VLAN subnets.
All ports are 10 GbE Locate ports sharing a single VLAN subnet.

Configuration procedures for each option are provided below.

Separate VLAN Subnet Configuration

To configure Locate port bonding with each port on its own VLAN subnet, do the following:

Step 1 Edit the Linux configuration as follows:

[root@460recorder92 ~]# ifconfig eth4

eth4 Link encap:Ethernet HWaddr 90:E2:BA:1E:3D:EC

[root@460recorder92 ~]# ls -l /proc/net/vlan/*

-rw------- 1 root root 0 Jul 2 14:58 /proc/net/vlan/config

-rw------- 1 root root 0 Jul 2 14:58 /proc/net/vlan/eth4.2102

-rw------- 1 root root 0 Jul 2 14:58 /proc/net/vlan/eth6.2103

Step 2 Edit the setup file and subnet table:

Note Beginning with Release 4.1.3, there is no longer a dedicated Locate port in the setup file.

[root@460recorder92 ~]# grep locate /arroyo/test/setupfile

service http locate port address 192.169.210.77

[root@460recorder92 ~]# grep ingest /arroyo/test/setupfile

ingest eth4.2102

ingest eth6.2101

[root@460recorder92 ~]# grep ixgbe /arroyo/test/setupfile

ixgbe adapters maxrate 9850

ixgbe 0: streaming 1 fill 1 ip 192.169.210.69 tport 0 cport 0 tgid 0

ixgbe 2: streaming 1 fill 1 ip 192.169.210.73 tport 0 cport 0 tgid 0

[root@460recorder92 ~]# cat /arroyo/test/SubnetTable

network 192.169.210.68 netmask 255.255.255.252 gateway 192.169.210.70 transport_source_ip 0 vlanid 2102 <<<--- eth4 vlan 2102

network 192.169.210.72 netmask 255.255.255.252 gateway 192.169.210.74 transport_source_ip 0 vlanid 2101 <<<--- eth6 vlan 2101

network 192.169.210.76 netmask 255.255.255.252 gateway 192.169.210.78 transport_source_ip 0 vlanid 2103 <<<--- shared vlan 2103 for Locate

The cserver Locate port is now ready.

Note When all cserver interfaces that host these services are down, the locate service is brought down. For this reason, it may take some time for the cserver to communicate with the router after restarting to confirm that the hosting interfaces are back up and that the L3 remote server connection is restored.

Step 3 Confirm the following /var/log/messages:

2015 Jul 2 12:46:45 460recorder92 [ 379.094260] The new timing adapter is eth4

2015 Jul 2 12:47:45 460recorder92 [ 439.064774] Link state reestablished on a fill adapter

2015 Jul 2 12:47:45 460recorder92 [ 439.070195] Start delay to reacquiring service address 172.22.99.92

2015 Jul 2 12:47:45 460recorder92 [ 439.076744] ** Monitor heartbeat packet transmit delay of 98310ms **

2015 Jul 2 12:47:45 460recorder92 [ 439.083424] Available HTTP Locate Port on service address 192.169.210.77

2015 Jul 2 12:47:50 460recorder92 [ 444.062845] Reacquired service address 172.22.99.92

2015 Jul 2 12:48:16 460recorder92 [ 469.998161] Service address assignment continuing

2015 Jul 2 12:48:33 460recorder92 [ 486.371199] Primary HTTP Locate Port on service address 192.169.210.77

2015 Jul 2 12:48:33 460recorder92 [ 486.379293] Started primary service for HTTP Locate Port address 192.169.210.77 on dedicated adapter 0 <<<--- finally hosted on 1st cserver IF (10GE)

At this point, the cserver will support locate resiliency on the available cserver interfaces.

Step 4 Physically disconnect and then reconnect the port cable to shut down and restart the cserver interfaces.

Shared VLAN Subnet Configuration

To configure Locate port bonding with each port sharing the same VLAN subnet, do the following:

Step 1 Configure the Linux setup file as follows:

[root@460recorder92 ~]# ifconfig eth4

eth4 Link encap:Ethernet HWaddr 90:E2:BA:1E:3D:EC

inet addr:192.169.210.69 Bcast:192.169.210.71 Mask:255.255.255.252

#service http locate port address 192.169.210.77

service http locate port address 192.169.210.83
